I think I had a miscarriage?

Chelsea

I’m Rh- trying to conceive…today I passed a larger clear sac. My period started yesterday but three days prior I woke up in the middle of the night with excruciating cramps that I can only compare to my “spontaneous miscarriage” from 14 years ago. I’ve never had this happen since. I know I should probably go to a doctor but I need insight first. Thank you.
